In this work, a promising solid-state laser material, Er-doped cadmium aluminum silicate glass, has been synthesized by solid-state reaction. Very intense emission at 1534 nm, corresponding to the [sup 4]I[sub 13/2]→[sup 4]I[sub 15/2] transition of Er[sup 3+] ions, was observed upon both 488 nm Ar[sup +] laser and 632.8 nm He-Ne laser excitations at room temperature. Possible cross-relaxation processes in the glass are discussed. © 2000 American Institute of Physics.
